UNITED STATES PATE T Drmcn CHARLES HOLLAND, OF MAXTON, NORTHOAROLINA.

LIFT-PU MP.

SPECIFICATION forming part of Letters Patent No. 412,501, dated October8, 1889.

Application filed April 29, 1889.

To all whom it may concern:

Be it known that 1, CHARLES A. HOLLAND, a citizen of the United States,residing at Maxton, in the county of Robesonjand State of NorthCarolina, have invented certain new and useful Improvements inLifting-Pumps; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention has relation to improvements in lifting-pumps, such as areused on farms and for domestic purposes generally. In pumps of thischaracter, when the water in the stock has leaked out, leaving the valvedry, it has been necessary to replenish the stock or barrel with waterin order to get a suction; but by my improvements the stock or barrel iskept supplied with water, so that the pump is always ready for use, aswill be readily understood by the following description.

Reference being had to the accompanying drawings, Figure 1 is averticalsection of my improved pump. Fig. 2 is a side view in elevation.

A designates the well, provided with a seat 1, on which the pump-stock Bis secured by means of bolts 2, passing through a flange 3, formed inthe bottom. The bottom 4 of the pump-stock is formed integral therewith,or, if separate, is made water-tight in its connections. In the bottom 4is an orifice or port, as shown,over which is secured avalveseat 5. Thismay be made in one piece or separate. In the latter instance thevalveseat has screw-threads at its lower end to screw in the bottom.This valve-seat is preferably made tapering, as seen in the drawings inFig. 1, being substantially a frustum of a cone in shape, on the top ofwhich is secured the valve 6, constructed in the form of a double disk.I have illustrated it as having -the ordinary puppet-valve.

C designates the plunger fitted to the bore of the stock and providedwith a suitable packing to renderit water-tight. In the cencient waterto be operative.

Serial No. 308,979. (No model.)

ter of the plunger is an orifice 7, over which is secured, or it may beformed as a part of the plunger, a valve-seat 8, which is preferablycone-shaped and hollow to fit over the valve-seat in the bottom of thestock. On the top of the valve-seat 8 is a valve 9, of any suitablestyle. Ihave shown it as apuppet-valve.

11 designates a bail secured to the plunger by any suitable means, andis for the purpose of raising and lowering the plunger. To the bail isfastened the pump-rod 12, which extends up through a hole in the top 14of the pump, and is connected to the handle 15, which is fulcrumed inthe handle-support 16, fixed to the topof the pump. The bail-bars mayconstitute a cage at the top over the valve to serve as guides to thevalve. It

will be perceived that the valve-seat extends up in the bottom of thepump far enough toalways hold sufficient water to start the pump. Thevalve being on top of the valve-seat, the water cannot escape until itcomes on line with the top of valve-seat. Consequently the pump alwaysholds sufii- The chamber of the'valve-seat in the plunger is of the samelength as the valve-seat in the bottom of the pump, so that when theplunger comes down to the bottom of the pump and over the lowervalve-seat the water is forced up through the valve in the plunger andflows over the packing around the plunger sufficient to make the pumpdraw water. The valve-seats are shown tapering, so that the plunger willnot strike in working; but they maybe made simply of tubes.

What I claim as my invention, and desire to secure by Letters Patent, is

1. A lift-pump having a valved piston provided with a conical seat, apuppet-valve thereon having its upwardly-extending stem loosely socketedin the lifter-head, and the two heads or disks with their coupling-rods,which form the carcass or frame of said piston, the lower disk being ofgreater diameter than the upper and provided with asuitable packing.

2. A lift-pump having an inlet-valve frame In testimony whereof Ia-ffixmy signature in formed with a conical seat, a double-disk presence oftwo witnesses. puppet-valve located thGIGOILSt plunger having a frame oftapering form, a conical el0n- CHARLES A. HOLLAND.
